Abstract: PURPOSE:To shut an optional part of a display screen for a person wearing the optical shutter type eyeglass by using a count of a horizontal synchronizing signal count means so as to reference an area designation table means thereby controlling an optical shutter drive means. CONSTITUTION:A control section 6 uses a count of a horizontal synchronization counter section 4 to reference an area designation table section 5 thereby controlling an optical shutter drive section 7. The optical shutter drive section 7 selects the optical eyeglass 8 to be the ON or OFF state. A picture generating section 1 sends a picture signal to a display section 2 and a synchronizing signal detection section 3. The horizontal synchronizing signal count section 4 resets a horizontal scanning line number and the control section 6 references the area designation table section 5 to retrieve corresponding data. When the OFF state of the optical shutter is designated, the optical shutter eyeglass 8 is set to the OFF state, and a person wearing the eyeglass cannot read the picture corresponding to the horizontal scanning number.

Filed: 1991-11-12
Abstract: PURPOSE:To enable a hunting action to cease as soon as possible or to be prevented from occurring in a water cooler by a method wherein a mixing three-way valve is changed in opening. CONSTITUTION:In a water cooler, a cold water is made to circulate in a closed loop composed of a cooled water 1, a water-water heat exchanger 3, and a mixing three-way valve 4 by a pump 2. A flow path of bypass is provided in parallel with the water-water heat exchanger 3, the mixing three-way valve 4 is made to change in opening by the instructions of a controller 8 to determine the flow ratio of the water-water heat exchanger 3 to the flow path of bypass. A mixing three-way valve drive motor 5 is made to rotate forward or inversely by drive signals outputted from the controller 6. When a current is applied so as to make the drive motor 5 rotate forward, the water-water treat exchanger 3 is enhanced in water flow rate and the bypass flow path is lessened in flow rate. When a current is applied so as to make the drive motor 5 rotate inversely, the bypass flow path is enhanced in flow rate and the the water-water heat exchanger 3 is lessened in water flow rate. At this point, water circulating in the close loop is kept constant in flow rate independent of the opening of the mixing three-way valve 4.
